RAILWAY.

Specification of Letters Patent.

Application led March 18, 1914. Serial No. 825,526.

To ZZ whom it may concern:

Be it known that I, VVTLLIAM PRATT, citizen of the United States, residing at Gran Valley, in the county of Garfield and State ,of Colorado, have invented new and useful Improvements in Railways, of which the following is va. specication.

My present invention pertains to metallic sleepers or ties and means for fastening rails thereto; and it consists in and advantageous construction described and definitely pointed out in the claims appended.

In the drawings accompanying and forming part of thisspecification: Figure 1 is va plan of a portion of a railway constructed in accordance with my invention. Fig. 2 is an enlarged detail section taken in theplane indicated by the line 2*-2 of Fig. 1, and illustrating my novel rail-seating and fastening means. Fig. 3 is a section taken in the plane indicated by the line 3-3 of Fig. l. Fig. 3 is a top plan view of one of the rail chairs, showing the transverse corrugw tions in the depressed seat thereof. Fig. 4 is a detail plan illustrative of a modification hereinafter specically referred to.

Referring by numeral ings,-and more particularly to Figs. 1 to 3 thereof: l, 1 are railway rails, which may be and preferably are of conventional type, and 2, 2 are metallic sleepers or ties that are constructed according to my invention. The said sleepers or ties are identical in construction, and therefore a detailed description of the one shown i Figs. 2 and 3 will suiiice to impart a definite understanding of all. The sleeper or tie referred to is formed in one piece of steel or any other metal compatible with the purpose of a .railway sleeper or tie. y It comprises a top wall, side walls and shallow end walls, and is designed tobe embedded in ballast, such manner as to enable the ballast toprevent movement of the tie in the direction of its width. The end walls of the tie are made shallow, as stated, and as indicated by 3 in Fig. 2, in order to brace the sides of the tie and at the same time permit water to pass from below the tie at the ends thereof. In the upper wall of the tie 2 are openings 3a, which extend throughout the width of the tie, and from the said openings 3a reduced openings l extend toward the ends of the tie,"

and also toward the middle of thetie, as illustrated. Arranged in the openings '3a are rail chairs the peculiar I hereinafter" to the .said draw-f anchor plate similar to These chairs 5 fare 'ar-r ranged flush with the upper side of the tie, and are provided with tongues 6 designed and adapted to snugly occupy the sub-open ings 4, this with a view to precluding move- Patented Sept. 29, 1914. v

ment of the chairs in the direction ofthe i width of the tie, and also with a view to removing any strain attendant on a tendency of the .rails to creep from the connecting bolts hereinafter described. It will also be noticed by reference to Fig. 2 that the chairs 5 are provided with depressed seats 7 of a size to snugly receive the bases of the rails. Arranged under the openings in the to wall of the rail and against said top Wal, are reinforcing and anchor plates 8. One of these plates is shown in Figs. 2 and 3, and by reference to Fig. 3, it will be noted that the plates extend the full distance between the side walls of the tie. The plates 8 are connected to the top wall of the tie. through themedium of bolts 9, Fig. 1, and the "plate 8 and the chair 5 are connected together by bolts 10. It will alsobe readily observed that the rails are both the chair 5 and the plate 8 by bolts 11, equipped with heads that overhang the base of therail.

By virtue of the construction described, the rails are strongly held to the sleepers or ties, and this without the imposition of un'- due strain upon the connecting bolts. It will also be manifest that when necessary the raill chairs and f astenings mayv moved and replaced with new chairs fastenings, without impairment inal tie.

In the modified construction shown in Fig. 4, a seat 13 is provided in a chair 5*ik and the said chair is arranged in an opening 3 formed in the upper side of the tie. I would also have it understood that in the modied construction the upper wall of the tie is connected by bolts 9 to a reinforcing the plate 8 of Figs. 2 and 3, while the chair is connected to said anchor plate by lbolts 10, and the rail is held in the seat 13by bolts 11, which serve also to connect the chair and the anchor plate together.

Transverse corrugation's 17 are provided in the depressed seats 7 of the chairs shown in Figs. 1 to in'order to lend additional stiffness and strength thereto, as well as to and rails.

be reof the orig AWith a View to cushioning the rails and preventing noise as Well as to insulate the rails from the ties so that the rails can be used as electric conductors I prefer to interpose cushions 18, of compressed paper or other suitable material, between the chairs 5 and the ties, as indicated by the heavy lack lines in Figs. 2 and 3.

vHaving described my invention, what I claim and desire to secure by Letters Patent, is

1. In a railway, the combination of a metallic sleeper or tie having a top wall and side walls and also having an `opening in its top wall extending throughout its width, an anchor plate arranged between the side walls and under the top Wall of the tie and the opening in said top wall, bolts extending through and connecting the top wall ci the t-ie and the anchor plate, a chair snugly occupying the opening in the top wall of the tie and resting iush with the upper side of the tie and having a seat that receives a rail, bolts extending through and connecting the chair and the anchor plate, and rail-holding bolts engaging the rail base and extending through and connecting the chair and the opening and sub-openings in saidV top wall, means connectingthe anchor plate top Wall, a chair snugly occupying the said opening and sub-openings in the top wall of t e tie, means connecting the reduced porto saidl tions or tongues of the chair with the anchor plate, and rail-holding means engaging the base of the rail and connecting the rail chair and the anchor plate.

3. The combination in a railway, of a rail, a sleeper or tie having an opening in its upper side extending throughout its width and also having sub-openings extending in opposite directions from said opening and longitudinally of the tie, and a rail chair receiving the rail and snugly occupying the opening and sub-openings of the tie and ar ranged Hush with the upper side of the tic land connected with the rail and the tie.

4. In a rail walls and under the top wall of the tie and the opening in said top wall, bolts extending through and connecting the top wall of the tie and the anchor plate, a chair snugly occupying the opening in the top wall o f the tie and resting Hush with the upper side of the tie and having a seat that receives a rail; said seat being provided with transverse corrugations, a cushion interposed between the chair andthe tie, bolts extending through and connecting the chair and the anchor plate, and rail-holdin, T bolts engaging the rail base and extending` through and connecting the chair and the anchor plate.

ln testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
